MVC :: How To Keep A Hidden Field Populated On Validation

Jan 31, 2011

I have a form in MVC3 that includes a check box to copy data if it is the same as a previous form. If the checkbox is checked, it populates the text box with the content from the hidden field. Here's a sample to illustrate what I'm doing:

[Code]....

When the box is checked, it calls FillInfo(), which uses DHTML to fill the TextBox called "ThisInfo" with the value of the hidden field "DefaultInfo."

Here's the problem: if the form fails validation (e.g. "ThisInfo" is a required field and is left blank), the hidden "DefaultInfo" box is getting cleared out -- which I DON'T want it to do. As a result, when the checkbox is clicked, it is copying empty data into the "ThisInfo" field.

State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?

Mar 23, 2011

I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.

I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

Web Forms :: Validation Fails When Fields Are Populated On Page_load

Feb 17, 2011

I'm writing a small web application in c# and i'm running into a small problem.

Basically, on page_load() my backend MySQL db is queried to bring back the user data, and that is then inserted into the textbox controls as below:

[Code]....

Now the problem occurs when the RequiredFieldValidator kicks in. In my form processing function, I call Page.IsValid(), it fails and displays the required message next to the required fields.

I was wondering if there is a workaround for this, or a better way to go about what i'm trying to do.

ASP.NET Validation Issue - DropDownList Being Populated Dynamically On Client?

Apr 28, 2010

I'm populating a DropDownList using JS on the client and validating with a RequiredFieldValidator.This works fine on the client but the Page.IsValid consistently comes back false on the server.Is this because the selected value wasn't in the DropDownList when it was first served to the page?What's the easiest way around this? (I need to leave server validation turned on)

How To Able To Assign A Value To My Hidden Field Control

Mar 4, 2010

how am I be able to assign a value to my hidden field control? I have this web service that returns member's ID and name (e.g. 0001-John dela Vega). In order for me to search for a member, I'm using an autocomplete extender, now, if in case that I found the member I'd like to assign its member id to a hidden field. I ask this because I'd like to change the way my web service return data so instead of displaying the member's id and name at the same, I'll just show its member name.

I have a hiddenfield, which I want to save the scroll position of asp.panel scrollbar during postback, and when during postback this value is called back to set the scroll position.

function SetScroll(val) {

you save data into a dynamic hidden field ,which is created dynamically during the handling of some postback event.what is the best way to retrieve it from this field upon a postback, (besides searching the request for the key of this hidden field and then retrieving the corresponding value as in the code below)?

{
bool found = false;
for (int i=0; i<this.Request.Form.Keys.Count; i++)

Updating A Hidden Field Via JavaScript?

Feb 3, 2011

I inherited some JavaScript that I was told to integrate into our ASP.NET site. I thought this would be straightforward but it's turning out to be a bit of a challenge.

The code looks something like this:

<SELECT id="Question1" name="Question" onchange="updateQuestion();">
<OPTION value="notChosen">--Please Select One--</OPTION>
<OPTION value="in">India</OPTION>
<OPTION value="de">Germany</OPTION>
<OPTION value="fr">France</OPTION>
<OPTION value="us">United States</OPTION>
<OPTION value="ch">Switzerland</OPTION>
</SELECT>

The goal is to get the value from this HTML control into ASP.NET, however this control itself is being dynamically generated by another chunk of javascript, so I can't just change this to an asp.net control. My solution was to add the onchange="updateQuestion();" method, this JS will take these SELECT tags and place the values into an ASP.NET control:

function updateSecQ() {
var sQuestion = document.getElementById('<%=sQuestion.ClientID%>');
sQuestion.Value = "";
var questions = document.getElementsByName('Question');
for (question in questions) {
if (questions[question].value != null)
sQuestion.Value += questions[question].value + ",";
}
alert(sQuestion.Value);
}

As you can see, that's looking to update an ASP.NET control:

<asp:HiddenField ID="sQuestion" runat="server" value="" />

This appears to all work, however when I goto the server side on the form submit I see that sQuestion.Value is still = "".

Javascript - Set Hidden Field Value After Postback.

Jul 29, 2010

I have a component that determines a value on a postback event.

protected void Button_Click(object s, EventArgs e)
{
HiddenField.Value = 5;
}

There's more involved in the value of course, but HiddenField is an asp:HiddenField control with runat=server set. I have in my javascript:

var id = $("#<%= HiddenField.ClientID %>").val();

The code in the javascript is set to be run only after the postback has occured (a different client click event) for the purpose of passing the hidden field value via QueryString to another URL (since i can't do a response redirect on postbacks and the client wants it in a different page anyway).

I tried adding:

ScriptManager.RegisterHiddenField(HiddenField, "Value", string.Empty);

To a !Page.IsPostback section of code, but the ID is still not set when the javascript is run.
